Title: Suction device for cream solder printing
IPC: B41F15/20
Filed: 1992-03-17
Abstract: PURPOSE:To prevent quality from lowering caused by omission of a part, inferiority in conduction, and short-circuit by preventing irregularity of coating and run of cream solder from occurring by a method wherein a projection part and a depressed part which are fitted to each other are formed on an opposed edge of each suction block, and the projection part is projected in a direction crossing a squeegee. CONSTITUTION:A suction block has a crest (a projected part) 35 and a valley (a depressed part) 36 at respective opposed edges like a gear tooth. Since dimensions are set so that the crest 35 is closely fitted to the valley 36 when respective blocks exist at a closed position, even when a squeegee 7 exists at any position of A, B, or C, the squeegee 7 is in a state of intersecting the crest. Since a contact part of the bandlike squeegee 7 comes to correspond to two positions of at least one block, when the squeegee is brought in pressure contact onto a substrate via a mask, there is no fear of generating warpage downwards.

Filed: 1989-04-13
Abstract: PURPOSE: To constantly attain the firm and positive seating of a retaining ring, and reject the retaining rings which fail to meet the specifications by providing a path length measuring system for measuring the diameter of the retaining ring and an electricity measuring system for measuring pressurizing force. CONSTITUTION: Resistance-wire strain gauges 10 are provided at projection parts 7 of a pressurizing device to convert the pressure on a retaining ring into a voltage in cooperation with an electronic measuring device to measure radial pressurizing force on the retaining ring 4. Further, a lever arm 12 is joined to one of pressurizing levers 6 to measure the position of the projection part 7 in the radial direction while the retaining ring 4 is under pressure, and the diameter of the pressurized retaining ring 4 is stored. Then, when the pressure is released in state where the retaining ring 4 is faced on the round of an annular groove, the retaining ring 4 is surely fitted into the annular groove to contact the end face 18 of an assembly bush 19.  At this time, a shaft is fixed, and a mounting head is moved in the axial direction to check the seating of the retaining ring 4 to the annular groove. When the retaining ring is not fitted into the groove, slippage of the shaft on the outer periphery, and displacement of the mounting head are produced, and these slippage and the displacement are recorded by a control mechanism.

Title: Automatic microscope device
Inventor: OGINO MASAYOSHI
IPC: G01N21/956
Filed: 1986-04-23
Abstract: PURPOSE:To prevent an inspector from being intoxicated, by preventing an image from being formed in an eyepiece part, when a microscope image flows in an observation visual field. CONSTITUTION:In case of confirming with the naked eye a defect of a wafer 1, which has been detected by an automatic external appearance inspection, only a defective part is observed at intervals by moving an XYZ table 2 at a high speed in order to shorten the inspection time. However, when an observation visual field is jumped at a high speed, the observation visual field flows at a high speed in the course of its movement, therefore, an inspector feels intoxicating. In order to avoid it, in this case, at the time of moving the XYZ table 2 at a high speed, a controller 13 transmits a shielding command to an operating device 18 simultaneously, so that the visual field is obstructed by a blind 17. In this way, the inspector can do without seeing a flow image in the visual field, therefore, it is prevented that he feels intoxicating.

Title: Tone arm lift mechanism for record player
Inventor: ITOU SEIJI
IPC: G11B3/08
Filed: 1978-07-28
Abstract: PURPOSE: To secure a gentle lift control for the tone arm with a simple constitution by stretching the lift arm supporting the tone arm lift axle via the heat expanding substance and securing the up-down movement of the lift arm with expansion of the heat expanding substance.  
     CONSTITUTION: Lift arm 6 which supports tone arm lift axle 5 via heat expanding substance 7. When the electric conduction is given to substance 7 via lead wire 8, substance 7 generates the Joule heat by the electric resistance of its own to cause the linear expansion with the tension loosened. As a result, the energy generated with compression of lift spring 9 is discharged to push up lift arm 6 toward arrow marking C. Accordingly, lift axle 5 is pushed downward to raise up tone arm 10. When the electric conduction is stopped to substance 7, substance 7 is immediately cooled down naturally to be contracted to the original size. Thus arm 6 lowers down arrow D, and accordingly axle 5 and then arm 10 als lower down.
